Problems solved by technology

The earliest solvent dyeing method, but it is limited to pure solvent dyeing of disperse dyes, the dyeing effect on synthetic fibers is better, and there is a problem of solvent pollution
Supercritical carbon dioxide dyeing appeared in the 1980s. So far, some pilot equipment has appeared, and some dyeing effects can be satisfactory, but it is also limited to the dyeing of synthetic fibers, especially polyester, and is difficult to apply to natural dyeing. The dyeing process of fibers (such as cotton, wool and silk, etc.) is mainly due to the poor solubility of supercritical carbon dioxide for hydrophilic compounds. Even if the disperse dye modification technology is used in natural fiber dyeing, the mechanical properties of dyed fibers If you are strong, you will be seriously injured
Reverse micelle dyeing is a new textile dyeing method that has emerged in recent years. It has the advantages of saving water and energy. However, the currently available reverse micelle system is quite limited, and there are some shortcomings that are difficult to overcome. For example, non-polarity in the system Solvents pollute the environment, endanger human health, and are difficult to recycle and reuse, which limits the promotion and application of this technology

Abstract

The invention discloses a reverse micelle system and an application thereof in acid dye dyeing. The reverse micelle system is characterized by comprising the following components in percentage by weight: 90%-98% of supercritical carbon dioxide, 1%-5% of a surfactant, 0-0.5% of an acid dye and the balance of water. Supercritical carbon dioxide dyeing is organically combined with reverse micelle dyeing; the supercritical carbon dioxide is taken as a non-polar organic solvent in reverse micelle dyeing due to the fact that the supercritical carbon dioxide is nontoxic, tasteless and not easy to combust and is an environment-friendly chemical solvent; in addition, the system only contains very little water of a reverse micelle-coated soluble dye; the amount of water can be greatly reduced; meanwhile, the carbon dioxide is recovered in the form of gas under the supercritical condition; the non-polar organic solvent, the surfactant and water can be easily separated; and recovery and cyclic utilization are achieved.

Description

Technical field: [0001] The invention relates to acid dye dyeing, in particular to a reverse micelle system and its application in acid dye dyeing. Background technique: [0002] The textile industry is one of the sectors with large water consumption and sewage discharge in my country. According to incomplete statistics, the annual discharge of wastewater has exceeded 1 billion tons, ranking the forefront of my country's industrial wastewater discharge. Among them, the discharge of printing and dyeing wastewater accounts for about 80% of the wastewater in the textile industry, and there are problems such as high chroma and complex components, and it has strong biological toxicity and seriously pollutes the ecological environment. For this reason, people have used physical, chemical and biological methods to treat printing and dyeing wastewater and made some progress. However, due to the huge amount of wastewater, it not only consumes a lot of manpower and energy, but also is...
